Understanding Huawei SD-WAN VN (Virtual Network) Topologies
Huawei SD-WANusesVirtual Networks (VNs)to providetraffic isolation and policy-based routingfor different services, branches, and applications.
#VN Topologies Can Be Different
Each VN (Virtual Network) can have its own topology.
Some VNs may usefull-mesh, while others may usehub-and-spokeorstar topology.
Different VNs can havedifferent routing and security policies.
#Example:
Corporate traffic (VN1)#Full-mesh topologyfor efficient inter-branch communication.
Guest Wi-Fi traffic (VN2)#Hub-and-spoke topologyto restrict inter-site communication.
Why is the Answer FALSE?
#All VNs do not have to use the same topology.
#Each VN can be configured independently with a unique topology, routing policy, and security settings.

ForSRv6 (Segment Routing over IPv6)deployment on abearer WAN, the following are essential:
IGP (OSPFv3 or IS-IS): Required for SID advertisement and SRv6 route computation ## BGP: Required when deployinginter-domain SRv6or for control plane distribution of VPN/service routes ## Not required:
MPLS: SRv6 replaces MPLS labels withIPv6-based SIDs##
BGP-LU: Used inMPLS-based inter-AS scenarios,not applicableto SRv6 ##
Correct answers: B, C

A). The device sends sampled data every second#Correct, since sample interval is 1000ms = 1 second.
B). The subscription mode is static subscription#Correct, as shown by Sub state: PASSIVE. Passive indicates astatic subscription.
C). The IP address of the device is 192.168.56.1#Incorrect- this IP address is thedestination (telemetry collector),notthe device's own IP.
D). The subscription name is Sub1#Correct, as per Sub name : Sub1.
Correct answer: C. The IP address of the device is 192.168.56.1- this is incorrect because it ' s actually the collector's IP, not the device ' s.

The incorrect statement is Option C, which says "A site can only belong to only one VPN." This is false because a single site can belong to multiple VPNs if needed. For example, in some enterprise designs, a site may be part of both the Finance VPN and the Management VPN by configuring multiple routing instances (VRFs) and policies accordingly.
Exact Extract - HCIE-Datacom VPN Technologies Chapter:
"A site may be associated with one or more VPNs, depending on business requirements. This is achieved through VRF and route-target configurations." Reference:
